Jackson, what is you signal chain? Mic? Effects? Amp? Man, from one harp player to another, you've got going on!
Jackson's pedal board is frequently in flux, but he's got a few different mics that he uses - often a modded SM-57 - and on his board he's got a Whammy pedal, chorus, delay, an anti-feedback pedal, an auto-wah... all sorts of fun toys. He also uses amps by this company called Harp Gear
(and he says thank you! :)
